Development charity ActionAid has launched a campaign to stop businesses claiming ownership of plants and their genes.

The charity claims the livelihoods of poor farmers in countries such as India could be threatened by the actions of organisations like US bio-tech firm Rice Tec Inc which has been given a patent for its type of basmati rice.

Farmers protest in India against US patents

ActionAid is urging the UK government to reverse its support for patenting and boycott a European Union directive allowing the practice.

But Rice-Tec argues that such a small company does not pose a threat to the big Indian rice industry.

Protest advertisements published in national newspapers on Monday warn that entire food crops could be next on the patent list.

Basmati, known as the "king of rice", is the costliest rice in the world and India is the leading exporter.

But in the paddy fields of Texas, the Rice Tec Inc company is growing a strain of rice which it advertises as "comparable to the best basmati rice, but different."

Cultural threat

Farmers in northern India, where most of the natural rice is grown, say there is a threat to India's culture and heritage.

ActionAid's protest, which includes lobbying World Trade Organisation talks on patenting, coincides with the Indian government's legal challenge to the US patent.
